An update of the kubernetes package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The Kubernetes kubectl cp command in versions 1.1-1.12, and versions prior to 1.13.11, 1.14.7, and 1.15.4     allows a combination of two symlinks provided by tar output of a malicious container to place a file     outside of the destination directory specified in the kubectl cp invocation. This could be used to allow     an attacker to place a nefarious file using a symlink, outside of the destination tree. (CVE-2019-11251)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3905 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing     Kubernetes application platform solution designed for on-premise or private     cloud deployments.

    This advisory contains the atomic-openshift RPM package for Red Hat OpenShift Container Platform 3.11.154.

    Security Fix(es):

    * kubernetes: YAML parsing vulnerable to Billion Laughs attack, allowing for remote denial of service     (CVE-2019-11253)

    * kubernetes: `kubectl cp` allows for arbitrary file write via double symlinks (CVE-2019-11251)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.
